Emergency command platform construction requirements

[ Huaqiang Security Network News ]
Wang Ansheng, director of the Disaster Reduction Center of the Chinese Academy of Sciences, once pointed out: "To improve the modernization level of emergency systems, we must provide a large number of data, images and decisions made on this basis as disaster relief services. Our decision-making should be supported by scientific analysis and statistics. It is necessary to establish a database of disaster relief materials, personnel and expert reserves and network them so that they can be immediately deployed in the event of a disaster or an early warning."
From the occurrence and disposal of the major snow and ice disaster in 2008, we can see that all levels of government basically started the corresponding emergency plan and arranged disaster relief and disaster relief according to the emergency disposal procedures. However, the loss of disasters is still huge. Apart from the objective reasons such as sudden bursts of snow disasters, wide range, high intensity, and weak basic conditions for preventing snow and ice in the south, some of the problems are rooted in the lack of emergency means, especially in Emergency information platform construction.

Emergency Command Platform Construction Requirements: Integrating Response Challenges
The emergency response to public emergencies such as snow, earthquakes and earthquakes is actually the government's transition from normal work to abnormal work. The resources relied on are mainly the existing basic networks and application systems of e-government, but using various technical means. By extending the application system, it is possible to improve the efficiency of command and dispatch of various government resources, and provide emergency decision-making for emergency commanders according to the emergency plan and the auxiliary decision analysis model.
The information platform and the business system together form an emergency command system. The business system is the core and foundation of the emergency system. The information platform is the means to realize the business system. The core purpose of the emergency command system is to strive to mobilize multiple departments and units in the shortest time to coordinate and implement together to effectively solve public emergencies. This requires the integration of various information and resources, and the departments and units can cooperate with each other. However, at present, there is no unified technical standard and organizational standard for the information systems and various resources of each special department. Therefore, the first thing that needs to be solved in the emergency command system is the problem of “integration”.
Emergency command platform construction requirements: system and business organic combination
In response to the crisis, the system will go ahead. The integration of business systems requires smooth communication and sharing among various departments. The introduction of “one case, three systems” provides institutional and legislative guarantees for the emergency command system, eliminates information barriers between departments, and ensures the integration of business systems. Sex. At the same time, the integration of information platform in the construction of emergency command system should be integrated around the IT infrastructure, especially in multimedia systems, data management, security management, etc., in order to realize the integration of business resources and various IT systems.
The emergency information platform usually deploys multimedia applications such as video conferencing systems, image access systems, and voice systems. How to clearly distribute the on-site images held by the emergency command center to each special department, and it is related to the real-time situation of each special command center. Improve the efficiency of emergency command.
The data in the emergency information platform is related to whether the command and dispatch of the emergency is timely, whether the disposal method is proper, and whether the disposal effect is satisfactory. However, these emergency data are distributed in various special department systems. How to effectively extract emergency data for centralized storage is a problem that has been plagued for a long time. In addition, in the event of an emergency, how to ensure that the key data is intact and present accurate and complete information to the commander is also a problem that needs attention.
Security has always been a key issue for all types of IT systems. The security issues facing emergency information platforms come from how to ensure the security of connections with external networks, minimize security threats from outside, and protect system security. On the other hand, Ensuring the security of the intranet, especially to prevent potential threats to the system from mobile access users.
Emergency command platform construction requirements: build a stable support system
Because the emergency information platform involves the integration of various complex systems such as network, security, multimedia, and docking with various special department platforms. Therefore, a reliable and stable basic support platform is the premise and guarantee for the stable operation of the emergency information platform. It can also be said that it directly affects the effectiveness and efficiency of emergency response.
The network is the basis of the overall emergency information platform. The stability and reliability of the network determine the stability and reliability of the entire emergency command system. In the actual scheme design, dual-core and aggregation layer dual-homing can be deployed in the core area of ​​the command center network to improve load balancing, mutual backup, and access link availability at the core layer of the network. Ensure the reliability of the emergency command system network. On the other hand, it can realize 10 Gigabit core switching, Gigabit to desktop access, provide a high-performance switching network for the command center, ensure the demand for network resources of various business systems, and also meet the future new business to the network. Demand.
In the face of various complex emergencies, the emergency system is often required to contact relevant personnel at the first time in order to conduct rapid meeting and dispatch and direct according to the real-time situation ahead. Therefore, a converged multimedia fusion solution can conveniently distribute the monitoring images to various venues, and the monitoring images can be completely digitally joined without the need of analog conversion, and the clarity of the images of the various venues is relatively high. On the other hand, through the deployment of IP voice gateways and terminals, various voice devices such as mobile phones and analog phones are connected to the emergency video conference, so that the front field personnel can join the conference by telephone or the like to report the situation on the spot. Combined with on-site images to provide commanders with comprehensive multimedia information.
It is an important requirement for the construction of emergency information platform to ensure the safe and stable operation of the emergency command information platform and ensure the confidentiality, availability and integrity of the information. According to the security level and physical location of the information, the entire system can be divided into security zones, and different security policies can be implemented for different security zones. In the WAN, remote security access and remote disaster recovery are adopted to meet the security, confidentiality and timeliness requirements of multi-sector remote data transmission. In the local area network, border protection and internal control solutions from outside to inside can be adopted for users. The network controls and audits to achieve unified monitoring and management of the entire network.
In order to ensure wide-area data integration and data protection in the emergency information platform, IP-based storage technologies can be used to deploy IP SAN devices in each special department, and integrate emergency-related data of each special department to disperse and heterogeneous data. The information is extracted to the emergency command center for centralized storage through the IP network, and the problem of decentralized emergency data storage and isomerization of the data structure is solved. In addition, when all the business systems in the emergency system are built on a unified data center, the business continuity of the data center becomes the key content of the information maintenance work of the emergency information platform. Through the construction of a complete online storage, near-line CDP system, remote disaster recovery system, and offline archiving system, the data of the emergency command center can be protected from all kinds of natural disasters, facility failures, misoperations and even malicious tampering. The data caused by the loss.
The emergency command system is a complex application system. Only through ordinary maintenance means, the management system is dispersed, the maintenance difficulty is increased, and the operation is complicated. Therefore, its integrated management system is based on the business application process model, adopts the service-oriented (SOA) design idea, assembles the componentized structure on demand, and integrates network management, video management, storage management, monitoring management and unified through a unified interface. Security and other functions can be integrated into the management of services, resources and users for users of emergency information platforms at all levels to help them achieve end-to-end management and fundamentally solve the management and maintenance problems.
